ABSTRACT:
The invention relates to a power entry module for supplying power from an outside source to equipment with which the power entry module is in association. The module is made up of a one piece housing divided into at least two compartments with a first compartment having means housed therein for connection to an outside power source. A second compartment includes respective fuse clips for use with different size fuses for routing power from the outside power supply through the fuses and into the equipment requiring the power. A voltage card enables selection of the outside power supply within predetermined ranges and converts the incoming voltage to that required by the equipment depending upon the position of the card. A cover is hinged to the housing and when in closed position with an outside power supply plugged into the power entry module, has means for preventing opening of the cover to prevent access to the fuse compartment to avoid the danger of shock. When it is an open condition without a plug plugged into the power entry module, it prevents such a plug from being plugged in and thus, maintains the contacts of the fuse clip in neutral position thereby avoiding the danger of shock to a user of the device.
